2.Main Features of Sodium Hydrosulfite:

It is a versatile chemical that's used in the manufacture of a variety of products we all use every day, 

from photographic film to wine; from fine writing papers to leather goods; from colored fabrics to metal recovery.

While the applications for this chemical workhorse are as vast and as varied as the industries that use it, 

in most cases, sodium hydrosulfite performs one of the following three roles:

1) As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons

2) As sulfonating agent, hydrosulfite adds sulfur to another chemical compound

3) As cation source, hydrosulfite adds a cation, or sodium, to a product system

Q:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
Q:What is the inorganic salt, is not the organic salt and is not the inorganic salt
There is no concept of organic salt inorganic salt inorganic salts in the class of chanting
Q:the absorption of inorganic salts is how to absorb the form
Root cell cell concentration is high, with the external soil moisture to form osmotic pressure, resulting in water and dissolved in water in the inorganic salt flow to the root cells, the absorption method is in the form of dissolved, so it is in the form of ions. If the salt can not be dissolved can not be absorbed, as for the specific water and inorganic salt transport can refer to 2017.7.25 know the daily newspaper.
Q:Why plasma osmotic pressure and protein, inorganic salt content
Plasma osmotic pressure is divided into crystalline osmotic pressure and colloid osmotic pressure.
Q:anybody here knows the difference of organic iron salt (ex. F.gluconate) vs inorganic (ex. F.sulfate)?
It it's organic, then the anion (the negative ion) is the conjugate base of an organic acid. If it's inorganic, then the original acid was inorganic (like H2SO4 making sulphates).
Q:Does the plant roots absorb inorganic salt ions must be active
Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
Q:Does the plant absorb some of the inorganic salt?
Plants absorb inorganic salts and do not necessarily absorb water.
Q:What to eat can promote the absorption of inorganic salts
Transpiration on the absorption of inorganic salts has little effect, the book or which exercises on the image shows the problem
Q:Can you die breathing in salt?
The boiling point of inorganic salts is extremely high due to the strength of their ionic bonds. The temperatures will kill you.
Q:What is the use of inorganic salts in plants?
Plants need inorganic salts, just as people need trace elements, the growth of auxiliary organisms can be through the leaves of the surface of the pores, with the water discharged together
